Tom, if you go into echolink,
here I have everything unchecked for index view under prefferences.
You have a standard tree view, when you get to the area you want, tab once 
and you will find all of the 0's.  I had to manually downarrow through the 
list.  You could link up from home, to find out the coverage area and PL 
tone.  You can off course link up to your Michigan friends just as well from 
Colorado as from Misouri.  Hope that helps.
